In case you were hoping to get a spot on the MS Balmoral when it sails from Southampton, England, on April 8 for its "Titanic Memorial Cruise" on the 100th anniversary of that earlier ship's fateful voyage, you're too late.

It's fully booked.

But, if you're interested in sailing from New York on April 10 aboard the Amazara Journey and meeting up with the Balmoral on April 15 at 41°43'57"N, 49°56'49"W in the Atlantic Ocean — where the Titanic sank on April 15, 1912 — there are still some spots.

On the 15th at the site of the Titanic's sinking, the ships plan to hold "a memorial service at 2:20 a.m. to commemorate the 100th year anniversary and to pay tribute to all the brave passengers and crew on board that fateful night."

The Balmoral is scheduled to then finish the Titanic's never-completed trip, docking in Halifax on April 16 and New York City on the 19th.

According to the BBC, the passengers on board the Balmoral will include relatives and passengers of those who were on the Titanic. The "unsinkable" ship's sinking after it struck an iceberg claimed about 1,500 lives. About 700 people survived.
